Star couple Blake Shelton and Gwen Stefani have won the CMT Award for Best Collaborative Video, for their duet song Nobody but you.

This is the couple's first-ever award win together, reports etonline.com.

The two hugged as they accepted the country music award from home.

"What is happening with my life?" Stefani asked.

"I told Gwen when I saw who the other nominees were in our category, I was like, 'That would've been cool, but I don't know what our chance of beating Justin Bieber are,'" Shelton said. "But here we are."

Shelton then thanked fans for voting.

"You guys are the ones that buy the records and come to the shows, and you vote on these things so we love you so much," Shelton said before the two singers said "I love you" to each other.

They even toasted with a martini.

"This means the world to us, more than you probably imagine," he added.

"This is a crazy pairing, but it's working!"

They were nominated alongside Carly Pearce and Lee Brice's "I Hope you're happy now", Dan + Shay and Justin Bieber's "10,000 Hours", Kane Brown featuring Nelly's "Cool again", Marshmello and Brown's "One thing right" and Thomas Rhett featuring Jon Pardi's "Beer can't fix".
